How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original.

Three quantum systems are involved. The actual teleportation protocol requires that an entangled quantum state or Bell state be created, and its two parts shared between two locations (the source and destination, or Alice and Bob). the four Bell states) on the two particles in her possession. [27] On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. For simplicity, we'll consider the case of teleporting the simplest possible quantum system – a qubit. It is inaccurate to say "an atom has been teleported". The left hand side of the equation is: where Ψi* is the adjoint of Ψi in the Heisenberg picture. However, there can be situations where two identical qubits are indistinguishable due to the spatial overlap of their wave functions.
Quantum teleportation is designed to send qubits between two parties. 0 But there is a subtle, unscannable kind of information that, unlike any material [12][13] As of 2015,[update] the quantum states of single photons, photon modes, single atoms, atomic ensembles, defect centers in solids, single electrons, and superconducting circuits have been employed as information bearers.[14]. Alice and Bob locally prepare known Bell pairs resulting in the initial state: In the case of the other three Bell projection outcomes, local corrections given by Pauli operators are made by Alice and or Bob after Carol has communicated the results of the measurement.
Alice's particle and Bob's first particle are entangled, and so are Bob's second and Carol's particle: Now, if Bob does a projective measurement on his two particles in the Bell state basis and communicates the results to Carol, as per the teleportation scheme described above, the state of Bob's first particle can be teleported to Carol's. . thereby putting C into an exact replica of The latest reported record distance for quantum teleportation is 1,400 km (870 mi) by the group of Jian-Wei Pan using the Micius satellite for space-based quantum teleportation.[9][10][11]. statistics. "This result could help to connect quantum computers with information capacities beyond qubits", says Anton Zeilinger, quantum physicist at the Austrian Academy of Sciences and the University of Vienna, about the innovative potential of the new method. A technical description of the entanglement swapping protocol is given here for pure bell states. These two classical bits do not carry complete information about the qubit being teleported. Your email address is used only to let the recipient know who sent the email. This is one of the foundational building blocks of quantum information processing. The research teams report this international first in the journal Physical Review Letters. Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else.

All possible such generalizations were discussed by Werner in 2001. Of course, Alice could simply physically send the qubit. The scanned information is sent to the receiving
